Researchers examining the auditory processing areas in the cerebral cortex in humans have better characterised the processing activities. Much like the processing of vision, the processing of sound involves ‘what’ and ‘where’ streams. The researchers in the study reported on here have investigated the ‘what’ stream and identified three components which analyse basic tones, multiple tones and speech sounds such as vowels. This better understanding will be useful into a number of illnesses in which speech is affected. There is a write-up here of a study published in the journal Age in which the researchers looked at the performance of sportspeople in a various fields. They found that peformance for swimmers peaked at age 21 and for chess grandmasters at 31. There’s been some interesting work from two personal genomics companies. Using a large sample size, the researchers at these companies have identified new gene associations with Parkinson’s Disease and estimate that up to 25% of the risk associated with Parkinson’s Disease is genetic. The study was published at PLOS Genetics One and the study is covered in detail at the Alzheimer’s Forum here. The authors of a meta-analysis with a large sample size (n=6122) concluded that whilst there is an association between Homocysteine levels and Alzheimer’s Disease causality has not yet been established and further studies are needed. In a German study (n-104), the researchers characterised the course of the illness in people with a diagnosis of Frontotemporal Lobar Degeneration. In their study 57% of the people in the study were still living at home and 40% were receiving non-pharmacological treatment.

The Alzheimer’s Society in conjunction with Tesco are holding a ‘Remember the Person Photo competition‘ to raise awareness. In Harlow, there are a number of activities including a collection at a Garden Centre, a reminiscence day, an information stand, singing session and tea dance. There is coverage of the work of HOPE – a group of people living with dementia who are raising awareness in West Sussex here. In Sheffield there are a number of activities including an event featuring a children’s TV presenter, a memory tree, balloon launch and singing. In Warrington the Warrington Arts Council for the Development of Music (WACIDOM) has organised a musical recital and there is also a tea event.
